Level 2 EV Charger: Misinterpretation of Input
CVE-2025-5747 is a high-severity misinterpretation of input vulnerability in Level 2 EV Charger from Wolfbox, with a CVSS 3.0 base score of 8.0 out of 10. It can be exploited from the same local network by an attacker with a low-privileged account, without any action from a user. Affected Level 2 EV Charger versions: 3.1.17 (main), 1.2.6 (MCU). The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.38% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.

Official description
WOLFBOX Level 2 EV Charger MCU Command Parsing Misinterpretation of Input Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installatons of WOLFBOX Level 2 EV Charger devices. Authentication is required to exploit this vulnerability. The specific flaw exists within the handling of command frames received by the MCU. When parsing frames, the process does not properly detect the start of a frame, which can lead to misinterpretation of input. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the device. Was ZDI-CAN-26501.
